Hello @kingdonkeykong ,
Thanks for your feedback.
After installing it, the measure on Pagespeed from Google was decreased a lot.
Site Kit only adds a meta tag just to recognize the plugin version & it doesn’t create any impact on Page Speed. You can remove that tag programmatically by using below code snippet in theme’s functions.php.
add_filter( 'googlesitekit_generator', '__return_empty_string' );
Furthermore, if you’d like to share your site URL we can look into this issue for you.
And there′s not support for Google Analytics 4 yet.
Just wanted to share a good news, beginning with version 1.36, released on July 7, 2021, Site Kit is adding the ability for users to create and add a GA4 property directly through the Site Kit interface.
Best Regards,
